arranged. Supposing that to form a neutral salt by the chemical combination of the acid and alkaline elements the acid element consists of. three parts, in bulk, and the alkaline element of one part, the addition of one part of starch to the acid and three parts to the alkali will make the two bodies alike in bulk. While I have stated, as an illustration, that one part of starch is mixed with the acid and three parts with the alkaline element of the baking-powder, it IS evident that a greater number of parts of starch may be added to each, provided that the relative proportions of the chemicals, as above, are maintained, so as to produce a neutral salt when the elements are chemically combined in the operation'of making bread.

In using baking-powder the general praotice is to slice out a portion of the bakingpowder from the can or box by means. of a spoon, which cuts down Application filed April 10, (No specimens.)

To all whom it may concern.-

Be it known that I, WV ILLIAM PITT CLOT- WORTHY, of the ci y of Baltimore, in the State of Maryland, have invented certain Improvements in the Packing of Baking-Powders, of
